Abstract.
Large concentrations of Lepidonotothen macrophthalma (Norman, 1937) were confirmed in the shallow areas of the Scotia Ridge east of Burdwood Bank in November 1984 and October 1986. To date, with the exception of Patagonotothen ramsayi (Regan, 1913), the mass occurrence of other species of Nototheniidae has not been observed in areas outside the Antarctic. This paper includes ranges of length and age, gonad maturity stage, and degree of stomach fullness and the total length of individuals when they reach first maturity.
